Dear Friends,
We all hope that the corona virus will get under control and we get back to a normal life.
The extremely great feedback from our traditional WBG Conference in Munich will continue. We have started planning together with AspenCore the event for the 14th -15th of December 2020.
The next highlight for WBG devices will be at PCIM. My podiums discussion takes place in Hall 7-549 on Wednesday the 6th of May in Nuremberg. The session will start at 13:30 to 15:30, first SIC followed by GaN.
Do not miss our Chinese version bodospowerchina.com. There is no better way to communicate. As a publisher I serve the world: one magazine, on time, every time.
Best Regards,
Bodo Arlt editor@bodospower.com

Wide Band Gap
Why are Ultra-Low On-Resistance SiC FETs Hot?
So Your Systems Can Run Cool!
Power semiconductor switches are typically used in circuits where reducing losses during current conduction without aggravating switching losses is of great benefit. In various circuit protection applications where the devices must carry current continuously, lower losses in the conduction state are beneficial to keeping system efficiencies high and waste heat generation at a minimum.
By Anup Bhalla, V.P. Engineering, UnitedSiC
Power Management
Solving the Power Density Challenge
Artificial intelligence (AI), smart cities, and autonomous driving are only a couple of megatrends that impact mankind and transform our way of living. They also pose some tough challenges to current state-of-the-art technologies in many related disciplines.
By Bastian Lang, Product Marketing Manager, Dr. Roberto Rizzolatti, System Innovation Engineer and Christian Rainer, System Innovation Engineer at Infineon Technologies
DC/DC Converter
Getting the Most Out of a DC/DC Converter
Small isolated DC/DC converter modules have been used for decades to efficiently match the supply voltage requirement of a load to the available power rail, to provide low-power auxiliary voltages such as a negative rail for an analog interface, for safety isolation or just to break ground loops for a particularly sensitive area of circuitry.
By Steve Roberts, Innovations Manager, Recom and Axel Stangl, Product Sales Manager, Rutronik
Intelligent Power
Imagine a World Without Switching Losses
Until recently, the power conversion industry's progress in efficiency, size, weight and cost have been principally driven by improvements in semiconductor transistors. To achieve these improvements, the engineering goals for new transistors were straight-forward: increase the stand-off voltage, reduce conduction and switching losses, and reduce costs.

Design Considerations for a GaN-Based High Frequency LLC Resonant Converter
This article evaluates the performance of Gallium Nitride (GaN) power transistors in comparison to Silicon Superjunction MOSFETs (Si SJMOS) and Silicon Carbide MOSFETs (SiC MOS) for the high frequency LLC resonant topology. It first introduces key transistor insights for achieving a high efficiency and high power density LLC resonant converter.

Design and Simulation
The Power of Dowell's Equations and Curves
The standardized curves of Dowell's equations are a superb tool for designing better high-frequency magnetics. It is not sufficient to simply use a wire or foil of one skin depth or less. Excessive losses can continue at high frequencies. A careful balance of layer count and wire or foil count is needed to reach an optimum design. Using the numerical curves, instead of the original equations, provides a shortcut path to better understanding of winding design.

Opto
Internal Faraday Shield and Small Ci-o Enhance Optocoupler Galvanic Isolation Performance
High voltage isolation in today's context involves integrating subsystems with large voltage differences and systems ground potentials. This enables isolation applications ranging from power supply, motor control circuit of servo automation systems and industrial robots, battery management systems, photovoltaic (PV) inverters, electric vehicle (eV) inverters, ultra-fast charging and wireless charging stations to data communication and digital logic interface circuits.

Packaging
Improving Vacuum Solder Reflow for Challenging Power Module Packaging
The Power Module Packaging Market is projected by some analysts to have a CAGR of nearly 10% from 2019 through 2025, driven by the competing demands for more global energy consumption and the push to reduce the impact of fossil fuels on our environment. Sustainable energy and savings through improved efficiencies will drive improvements in the chip and packaging technologies used in power electronics.

Magnetic Components
Proper Validation of Output Choke: Same Shaped Ferrite vs. Dust Core
Output chokes for Switched Mode Power Supplies (SMPSs) normally operate for a DC load, where a bias magnetic field (HDC) is generated under operation of the magnetic cores. For the emerging mega-watt applications with SiC power devices, the proper validation of output chokes is of great challenge. Basically, there are two criteria for magnetic component design, which are from thermic aspect or from the magnetic nature.

Power Supply
Gaining 2.5%+ in PFC Efficiency at Low Cost
For low-cost and simple implementation, power factor correction (PFC) has historically been achieved by simple diode bridge rectification and a single-switch boost converter. This arrangement however has significantly reduced efficiency at low line, requires bulky magnetics, large heatsink and fans with high airflow. ICERGi PFC solutions can offer 2.5%+ improvement in efficiency at a cost comparable with the conventional approach.

What Makes a Good Magnetic Design?
The story of magnetics in Europe has many important characters including many who have been in the industry since the 80's. It is not possible to analyze what makes a good design without these people. I'm not referring to the researchers or the brilliant engineers, but rather the individuals who have been looking for the materials, winding the coils and repairing winding machines.

Hybrid Converter Simplifies 48 V/54 V Step-Down Conversion in Data Centers and Telecom Systems
There has been a shift in data center and telecom power system design. Key applications manufacturers are replacing complex, expensive isolated 48 V/54 V step-down converters with more efficient, nonisolated, high density step-down regulators (Figure 1). Isolation is not necessary in the regulators' bus converter since the upstream 48 V or 54 V input is already isolated from hazardous ac mains.
